1) 2
2) 4
3) 6
4) 8

Answer 1

4) 8 The correct answer is option 8 inches, which is the minimum diameter of a rainwater tank access opening that must be secured with a lockable device or other approved method for safety and security reasons.

Step-by-step explanation:

The correct answer is option 4) 8 inches. Rainwater tank access openings that exceed 8 inches in diameter must be secured to prevent tampering and unintended entry. This safety measure is mandated to ensure that individuals, particularly children, cannot accidentally fall into the tank, and to prevent contamination or interference with the water supply.

The use of a lockable device or another approved method is standard to secure such large openings. Moreover, this security protocol helps maintain the quality of the stored rainwater, keeping it safe for all intended uses, whether for irrigation, non-potable household uses, or potentially for drinking after proper treatment.
